Looks like Rocket B beat me to it...

...
Captain ( or a bypassed Captain) - $3,000 times years and months of service credits accrued by the crewmember (not to exceed thirty (30) years).

First officer - $2,400 times years and months of service credits accrued by the crewmember (not to exceed thirty (30) years). So for those who never upgrade a 20% hit.

Note - if you're an FO for 18 years and captain for 1 week or so, you get the captain pension for the whole duration of your employment. So you need to be a captain for 1+ day to get the captain pension. (at least that's my understanding?)
